little-seen books can find more life

Google book search is giving more life to little-seen books. Googlers may find older, out-of-print books that wouldn't be easily findable in any other search. Profit doesn't seem to be the point of this venture, nor should it be. The point of this venture should be education, to help Googlers in research and exploration. I understand if publishers of books still under copyright would like some sort of payment for providing texts, but I hope that more will be available freely, like a library.
